Sprint has announced today that it is set to acquire 100% ownership of Clearwire in a deal worth $2.97 per share — or roughly $2.2 billion. The carrier says it plans to utilize Clearwire’s 2.5 GHz spectrum, which will be migrated to 4G LTE standards, to achieve “operational efficiencies and improved service for customers.”

While the iPod touch is a terrific little device, it would be so much better if Apple gave it a data connection. It’s so frustrating when you quickly want to check on a sports score or load up a map and you’re in an area where there’s no Wi-Fi connection. Thanks to FreedomPop, however, you can now pick up a new case for $99 that comes with built-in WiMAX.

Japan’s third-largest carrier is reportedly in talks to buy control of Sprint, according to two people familiar with the matter. SoftBank wants to snap up two-thirds of the company with a stake worth “more than” 1.5 trillion yen ($19 billion), and it’s also eyeing Sprint’s partner, Clearwire, too.

Earlier this year, we reported on the plans by NetZero and FreedomPop to offer free 4G mobile broadband in the U.S. over ClearWire’s WiMax network. Both companies planned to operate on a freemium basis where users get a limited amount of data each month and can buy more if they choose.

This week, a company in the U.K. called Samba joined the free broadband bandwagon with a model that’s ad-based and freemium in nature, making it somewhat similar to NetZero’s original business model from the good old days of dial-up service.
